Question

注意：我是开发人员的Javaee新手。我的问题似乎很简单，但我无法理解，我创建了一个简单的Maven项目，当我尝试在maven中构建它并编写＆＃34; wildfly：deploy＆＃34;我遇到了部署＆＃34;＆＃34; .war的问题，这是.log：

有人可以帮助我吗

Answer 2

很简单，你可能有一些冲突的API（特别是这里的javax.servlet-api）。

尝试通过更改pom.xml中的范围，提供的范围只会在编译时放置依赖关系，并且依赖关系不会在运行时发生冲突，Wildfly提供了默认的javax servlet依赖关系。 / p>

像：

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.1.0</version>
  <scope>provided</scope>
</dependency>

这样，您提供的servlet api不会与服务器提供的那个冲突，并且只有在编译时才会出现依赖关系。
（P.S - 服务器也提供javax.servlet），如果您已经使用过maven install，只需从库中删除javax.servlet-api并再次执行maven install

maven项目+ wildfly + deploy .war
